Thanks.

You are welcome. Thank you for your patience.

You can put alsa-driver and alsa-kernel in the same directory level. Make in alsa-driver will create a symlink automatically from ../alsa-kernel.

My procedure is changed: cd /usr/src/ rm -rf alsa-lib rm -rf alsa-utils rm -rf alsa-driver rm -rf alsa-driver hg clone http://hg-mirror.alsa-project.org/alsa-lib alsa-lib hg clone http://hg-mirror.alsa-project.org/alsa-utils alsa-utils hg clone http://hg-mirror.alsa-project.org/alsa-kernel alsa-kernel hg clone http://hg-mirror.alsa-project.org/alsa-driver alsa-driver pushd alsa-lib ./hgcompile && make install

To be sure: you are using 32bit version, right? For 64bit, the library path might be /usr/lib64, instead of /usr/lib (depending on distro).

popd pushd alsa-utils ./hgcompile && make install popd cd alsa-driver ./hgcompile && make install popd # Build completed successfully. Yay. /usr/sbin/alsaconf # Chose 'hda-intel VIA Technologies, Inc. VIA High Definition Audio Controller" /usr/bin/alsamixer -Vall

So far so good.

There are 2 'CAPTURE' columns where I maxed levels. 'Input So' is set to 'Stereo M'

Attach the generated file via "alsactl -f somefile store" instead of ascii art. This contains the all mixer information.

It's a user error :) The usage below, -D plug:spdif, is correct, though.

OK, this is a bug in the recent alsa-lib. I fixed it now on HG tree. Please update your alsa-lib repo (maybe better from hg.alsa-project.org).
